Type 1 diabetes, also known as juvenile diabetes, is a chronic condition where the pancreas produces little or no insulin. Insulin is a hormone essential for converting glucose (sugar) into energy. This lack of insulin leads to high blood sugar levels, which can cause various health complications if not managed properly. People with Type 1 diabetes typically require lifelong insulin therapy, which can be administered through injections or an insulin pump. The exact cause of Type 1 diabetes is not fully understood, but it is believed to involve an autoimmune response that attacks insulin-producing cells in the pancreas.
